Referring now more particularly to the drawings, it will be understoodthat in the embodiment herein disclosed, my improved bed frame (Fig. 1)consists in general of a pair of side rails 2| and 22 which aresubstantially L-shaped in cross section, and which are constructed,arranged, and secured together as herinafter described.

Each of the modified forms shown in Figs. 2, 3, 4, and 5 employ similarside rails, but utilize different means for securing them together aswill appear more particularly hereinafter.

Referring again to Fig. 1, it will be understood that the side rails 2|and 22 are longitudinally slotted, asat 2 3 and 24, to accommodate bolts25,

and 26 secured to the underside of the extension rails 21 and 28, whichslidably engage the side rails 2| and '22 so that the latter may be ineffect lengthened. Wing nuts 29 are positioned on the lower ends of thebolts 25 and 26 so that the extension rails 21 and 28 may be secured inpre- 7 determined position to the side rails 2| and 22.

The side rails 2i and 22 have inverted L- shaped members 30 securedthereto to provide guides and thrust members to prevent the displacementof the extension rails 2? and 2:8 from the side rails 2| and 22. g

In each of the forms shown in Figs. 1, 2, 3, and 5 short end rails 3|,32, 33 and 34 are provided.

These end rails are comparatively short, and are formed by cutting andinturning the ends of the side rails 2| and 22 and the extension rails2'5 and 28, or by welding, or otherwise securing the same to the ends ofthe side rail extensions 2'! and 28. Each of the bed frames is providedat each corner with an adjustable leg 35 (Figs. 8 and 14) which aresecured to the side rails and end rails by means of bolts and nuts 38.Each of the structures illustrated in Figs. 1, 2, 3, and 5 is providedwith additional legs 35A which serve to support the linkage betweenthe'side rails 2| and 22 as hereinafter described.

The elements just described are all found in i the embodiments shown inFigs. 1, 2, 3 and 5, and function in the same manner throughout theseveral modified forms shown in those figures, and will therefore bearthe same reference characters throughout said figures.

The side rails 2| and 22, and the extension rails 2'! and 28 (Fig. l)are hingedly secured together by means of arms 31, 3B, 39, and 38, whichare pivoted at their respective ends, as at M, to angle plates 42 whichare welded or otherwise suitably secured to the end rails 3|, 32, 33 and34, and pivoted at their opposite ends, as at 63, to linkage plates 44to the underside of each of which is secured-the leg 35A. 7

The arms 31, 38, 38 and G are each slotted, as at 5, to accommodate abolt 46 which extends through a slot 4'! formed in the secondary arms 14? which are pivoted respectively at one end, to lugs 49 secured to eachside rail 2| and 22 and extension rails 2! and 28. Each of the bolts 48has a wing nut at the end thereof so that the pivoted arms justdescribed may be locked to each other in predetermined positions ofadjustment. Leveler blocks 58 are provided on the side rails 2| and 22to compensate for differences in height and width caused'by theoverlying of the side rails 2| and 22 by the extension rails 21 and 28.

In Fig. 2 the arms 52, 53 and 54 are each pivoted at one end to anchorplates 55 secured by welding or other suitable means at the juncture ofthe side rails 2| and 22 and the end rails 3|, 52, 33 and 34. The arms5|, 52, 53 and 54 are also pivoted at their opposite ends to linkageplates 55, and are provided with cooperating teeth 5? which frictionallyengage one another and serve as means to help hold the arms 5|, 52, 53and 54 in predetermined adjusted position. The arms 5|, 52, 58 and 54may be locked to the plates 55 by means of wing nuts 55A. 7 In Fig. 3the arms 58, 59, 60 and 6| are pivoted, as at 62, to the linkage plates83 and 54, and are adjustably bolted, as at 85, to slotted anchor plates56. In this embodiment, the side rails 2| and 22 are split, as at El,and are provided on their undersides with hinges 68 whereby thesiderails 2| and 22 may be folded in half upon the removal of the legs 35.Abutment blocks 69 reinforce the hinged joint when the side rails are inthe position shown in Fig. 8. In Figs. 10, 11, and 1.2 I show modifiedforms of the abutment blocks 18.

In the modification shown in Fig. 4, the side rails H and 72 are fixedin length, but the end rails '58, M, 75 and 15 are adjustable and areprovided with slots T! to accommodate bolts 18 4 which extendtherethrough, and are secured by wing nuts 19. The end rails 73 and T5are provided with thrust members and guides similar to the members 31]previously described. With this structure the side rails H and 12 may beextended to the positions shown by the dotted lines in Fig. 4.

In Fig. 5 I show a further modification in which the side rails 2| and22 are pivotally secured together by means of pairs of arms 8|, 82, and88, which are pivoted, as at 84, to the side rails, and as at to thelinkage plates 86. In this embodiment auxiliary arms 8! and 88 arepivoted to the end rails 3| and 32, as at 89, and are adapted to engagebolts 90 which extend through corresponding slots formed in the arms 8|.The pairs of arms 8| and the auxiliary arms 8! and 83 are locked inpredetermined position by the bolts 98 and wing nuts 9|. In thisembodiment the linkage plates 88 are connected by means of arms 92 and93, which are secured to the plates 88 by means of welding, or othersuitable means.

In Figs. 14, 15, and 16 I illustrate in detail one of the leg assemblies35. In this embodiment, the leg 35 consists of a top plate 94 havingholes 95 therethrough adapted to accommodate the bolts 88. The legproper comprises outer plate 96 and inner plate 97 which are curved, asshown in Fig. 16, to provide rigidity and strength. The outer plate 85is inturned, as at 98, to provide guides for the inner plate 91. Anadjusting screw 99 extends from the underside of the top plate 95 or"the outer plate 96 and through the inturned top portion ||l| of theinner plate 91, and lock nuts I02 and H33 are provided to lock theplates 96 and 97 in predetermined position. A caster me is secured to aU-shaped bracket I05 which is secured to the inner plate 91 by welding,or other suitable means.
